The different colors in antisera A, B, and D (often mistaken as O) are used for easy identification during blood typing. Each antiserum reacts with a specific antigen on red blood cells, so adding distinct colors helps medical professionals quickly distinguish between them and reduce the chance of error.
Here's a breakdown:
1. Antiserum A (usually blue) – tests for the A antigen.
2. Antiserum B (usually yellow) – tests for the B antigen.
3. Antiserum D (often colorless or clear) – tests for the Rh (D) antigen to determine positive or negative blood type.
The colors have no effect on the antisera's function; they're simply visual aids to ensure the accuracy and efficiency of blood typing tests.
